Hey man thanks for the reply YEAH! i had a feeling it could be coil pack & dfi, getting lube mobile to look at it tomorrow morning so hopefully i get some luck..

I also had another mechanic test drive it today could also be fuel pump. I changed the spark plug leads today myself first time started up but seem to of made the problem worse lol...
